Wearing a $242 Birdie jacquard shirt dress by Irish designer Orla Kiely and Aquatalia boots, the Duchess of Cambridge, 30, visited students at Rose Hill Primary School in Oxford, England, Tuesday. Inside the classroom, Middleton wore an apron that read "Miss Catherine" on the front as children worked on the poem "The Owl and The Pussycat."

On Monday, it was announced that Middleton's father-in-law, Prince Charles, 63, will visit Norway, Sweden and Denmark from March 20-27. The trips mark the beginning of his official overseas celebrations of The Queen's Diamond Jubilee, where Charles and Camilla Parker-Bowles will be guests of the Sovereign Head of State.
